It's a source of some significant regret that Keybase was acquired by Zoom, and the subsequent loss of street-cred that ensued - as I'd swung a few groups over, and really appreciated some of the features (you don't need a mobile phone number, you add / block people as needed (not phone numbers out of your contact list), and the effectively syncthing-alike feature of a synchronised file system you could share with specific persons or groups of persons.)
